Quizplus · Accepted Answer

The corpus callosum is the structure that connects the two hemispheres of the brain and allows for communication between them. As it grows and develops, it enables more efficient coordination between the two sides of the body. Choice B is incorrect because limb length has no direct relationship to coordination, and choice C is incorrect because lateralization refers to the specialization of each hemisphere for certain functions, not coordination. Adequate calcium in the diet may be important for overall health but is not directly related to coordination.
